Maintenance of sinus rhythm after atrial defibrillation. [PDF]

Heart, 1970
The long-term results of 356 episodes of atrial defibrillation by DC shock carried out in 250 patients are reviewed. In 78 per cent of the cases, atrial fibrillation recurred by the end of 12 months in spite of the administration of quinidine or procainamide or propranolol, singly or combined.

Impact of Renal Impairment on Beta-Blocker Efficacy in Patients With Heart Failure. [PDF]

, 2019
BACKGROUND: Moderate and moderately severe renal impairment are common in patients with heart failure and reduced ejection fraction, but whether beta-blockers are effective is unclear, leading to underuse of life-saving therapy.

PFKM‐Driven Lactate Overproduction Promotes Atrial Fibrillation via Triggering Cardiac Fibroblasts Histone Lactylation

Advanced Science, EarlyView.
The upregulation of PFKM activates glycolysis, thereby enhancing lactate production in atrial tissue. Atrial lactate accumulation promotes global lactylation and H3K18 lactylation in atrial fibroblasts. P300‐mediated H3K18 lactylation up‐regulates TGF‐β1 transcription, leading to fibroblast activation and thereby contributing to atrial fibrosis.

Comparison of the Relationship Between Inflammatory Markers and Atrial Fibrillation Burden

Anatolian Journal of Cardiology, 2023
Background: Atrial fibrillation is a complex disease with irregular ventricular response and tachycardia as a result of irregular and rapid contraction of the atria, with poor cardiovascular outcomes unless treated. Various mechanisms are involved in its

Transient unexpected improvement of AV conduction: What is the mechanism? [PDF]

, 2006
This ECG was recorded from a 93 year old patient with a previously documented third degree AV block and an underlying LBBB. The twelve lead ECG demonstrates sinus bradycardia at a rate of 52 beats per minute, a PR interval of 230 milliseconds, and a ...

A Novel Cranial Bone Transport Technique Repairs Skull Defect and Minimizes Brain Injury Outcome in Traumatic Brain Injury Rats

Advanced Science, EarlyView.
This study introduces a novel, safe, and effective surgical technique: Cranial bone transport (CBT) to improve traumatic brain injury (TBI) outcomes in rats. CBT significantly accelerated skull defect bone repair in addition to its promoting effects on neurological function recovery. This work provides an alternative therapy for patients suffering from

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

Atrial Fibroblasts‐Derived Extracellular Vesicles Exacerbate Atrial Arrhythmogenesis

Advanced Science, EarlyView.
Exosome miR‐224‐5p derived from angiotensin II‐treated atrial fibroblasts creates a substrate for AF by promoting atrial electrical remodeling. Increased exosome miR‐224‐5p enhances AF susceptibility by inhibiting CACNA1c expression and decreasing ICa current of atrial cardiomyocytes.
